NBR-PVC
NeoPolyTM NV ( NBR & PVC )
NeoPolyTM NV is a blend of NBR & PVC in various ratios. The blend of NBR & PVC maintains individual properties of both NBR & PVC. Vulcanzites based on NeoPolyTM NV exhibit excellent ozone resistance, fuel resistance & abrasion resistance.
Applications:
- Moulding such as auto parts, gaskets, oil seals, safety shoe soles & printing rollers.
- LPG hoses & tubes with flame retardant properties.
- Expanded sheets for insulation.
- Rubber sheets and extruded rubber parts.
Advantages:
- Economical compounds with excellent physical properties.
- Improved fuel resistance automotive application.
- Improved ozone resistance of NBR.
- Improve low temperature resistance.
Packing:
25 kgs coated paper bags
